> It would be really useful to allow the ability to specify a different Mapper
> for the {{ImportTsv}} class to use than the current {{TsvImporter}}. This
> would allow transformations to be made on the input data before being added
> to HBase. One suggestion is to add a new command line option to specify a
> user defined mapper (UDM?). Or maybe instead we just refactor it to be
> extended where a subclass can specify a new mapper.
> The mapper is statically defined and bound to the job though, so I'm not sure
> of the best way to make it dynamically plug-able. Suggestions welcome.
